PELLEGRINO DE BENEDICTIS, OF NEW YORK, N. Y.

ROPE AND CORD MAKING MACHINE.

Application filed April 22, 1914-.

To all whom it may concern:

Be it known that I, lnnnnonrxo DE BENE- DICTIS, residing at 362' Broome street, borough of Manhattan, in the city and county of New York, State of New York, have invented certain new and useful Improvements in Rope and Cord Making Machines, of which the following is a specification.

The invention relates to a rope or cord making machine, and more particularly to the class of thread twisting machines for producing twisted rope or cord.

The primary object of the invention is the provision of a machine in which a plurality of threads and a filler may be twisted for the formation of a twisted cord or rope of any desirable length, during the continued operation of the machine.

Another object of the invention isthe provision of a machine in which the finished cord or rope, when twisted, will be stretched taut and wound upon a winding spool which is actuated simultaneously with the remainder of the machine during the operation;

thereof.

A further object of the invention is the provision of a machine of this character which is simple in construction, thoroughly reliable and efiicient in operation, and inexpensive in manufacture.

Figure 1 is a front elevation of my device. Fig. 2 is a side elevation thereof. Fig. 3 is a section on line 33 of Fig. 1. Fig. 4 is a perspective of the stretching and positioning rollers. Fig. 5 is a section on the line 55 of Fig. 2. Fig. 6 is a section on the line 6(3 of Fig. 1. Fig. 7 is a section on the line 77 of Fig. 1. Fig. 8 is a diagrammatic view of the drive connections of the twisting device.

Similar reference characters indicate similar parts throughout the device.

Referring to the drawings the machine comprises a base 1 which supports a frame consisting of the inverted U-shaped member 2, upright 3, cross bar 4 and the supporting member 5.

.An upright shaft 6 rotatably mounted in the base 1 and a lug 7 extending from the cross 2 of the U-shaped member 2 is provided.

Mounted between the supporting member 5 and feet 8 attached to the base 1 are a pair Specification of Letters Patent.

of rotatable frames 9 carrying spools of cotton 10 and idler rollers 11 and 12. The rotatable mounting of the frames 8 consists of the hollow shafts 13 and the shafts 14: extending through the supports 8 and pro vided with sprocket wheels 15. The sprocket v wheel 16 is provided upon shaft 6 and connected to the sprocket wheels 15 by a chain 17.

Above the supporting member 5 are rotas tably mounted on hollow shafts 18 a pair of disks 19. These disks support in any su table manner as by the standards 19 a plurality of spools of silk 20. The upper extremities of the hollow shafts 18 are provided with disk like heads 21 having slots forming guides for the threads from the spools of silk. The disks 19 are rotated by means of sprocket Wheels 22 mounted upon the hollow shafts 18, sprocket wheel 23 mounted upon the upright shaft 6 and sprocket chain 24 connecting these wheels. Immediately above the disk members 19 and secured to the frame 2 are a pair of arms 25 and 25.

Mounted upon each of the arms 25 and 25 are a pair of sprocket wheels 26 mounted upon hollow shafts. Mounted upon the body of these sprocket wheels are upright standard members 26 carrying three idler pulleys 2-7, 28 and 29. These sprocket wheels are driven by the upright shaft 6 by means of gear wheel 30, gear wheel 31, shaft 31, sprocket wheels 26 and sprocket chain 31".

It will be seen that the rotation of the sprocket wheels 26 also causes the rotation of the uprights and the idler pulleys carried thereby and that the rotation is in a reverse direction to that of the disks and frames. Also mounted upon the arms 25 and 25 are a pair of upright arms 32 carrying idler pulleys 33 and 33.

The U-shaped member 2 is provided with a medial cross 2. Carried by this cross and the upper cross member of the U-shaped member is a frame member A. This frame provided at its lower end with a sprocket wheel 87 and a bevel gear 38. The bevel gear 38 meshes with bevel gear 39 mounted on a shaft to which extends through the frame member A.

On the opposite end of the shaft 40 is a gear Ll which in turn meshes with the gear &2 mounted on a shaft f?) also extending through frame member A. On the oppos te end of this shaft is mounted a gear as which meshes with a gear 45 mounted in a slot 46 in the frame A. The object of this slotted mounting is to allow of a change of gears which becomes necessary when different sizes of cords are being made by the machine. 'lhis gear 45 meshes with the gear upon roller 35. e

As the sprocket wheel 27 is connected by a sprocket chain 4:7 and sprocket wheel to to the upright shaft 6, it will be seen that the rttation of the upright shaft 6 transmits motion to the roller 85.

Swingably connected to the cross bar 4 and opposing the frame A is a second frame B carrying rollers a9 and 50.

'lhe roller 4-9 is provided with grooves 4-9 similar to those provided in the roller 5-1. The rollers 35 and 50 are covered with rubber or cloth for the purpose of preventing the slipping of the strands as they pass there over.

ihe roller 50 is interposed between the rollers 3i and carried by the frame A and is provided with gear teeth meshing with the teeth of these two rollers, and the roller l9 is also provided with gear teeth which mesh with teeth on roller 34. The frame A is provided further with an idler roller 51 and the frame B with a similar roller The upper extension of the hollow shaft 36 is provided with a bevel gear 52 and forms a bearing for a rotatable standard 53. This standard will be rotated at a speed independent of the speed of the hollow shaft. Carried by the standard 53 is a winding spool 5i mounted upon a shaft journaled in the standard. One end of this shaft is provided with a sprocket wheel 55.

Mounted in an arm of. the standard is a shaft 56 provided at one end with a bevel gear 57 meshing with the bevel gear 52 on the shaft 36. The opposite end of this shaft is provided with a sprocket wheel 58 connected to the sprocket wheel 55 by a chain 59.

The upright shaft 6 may be rotated in any suitable manner, as by a belt wheel 60 secured thereto operated by a belt driven from any suitable source of power.

The operationof the device is as follows: The cotton is drawn from the spools 9 and over the idler pulleys 11 and 12 up through the hollow shafts 13 and 18 through the disk like heads 21 through the hollow mountings of the sprocket wheels mounted thereabove and over the idler pulleys 27, 28 and 29 carried by the standards thereon. In passing through the hollow shaft of the sprocket wheels it is covered by the threads of silk from the spools which are applied by the twisting motion supplied by the rotation of the disks upon which the silk spools are mounted. After passing over the idler pulleys 27, 28 and 29 the respective cotton threads pass up over idler pulleys 33 and 38. The strand with its added covering which passes over the pulley 83 then passes over the roller 49 and thence over the idler pulley 52 on the frame B. The strand passes around this roller three times in order to make the said strand firm and cause the rollers to draw without slipping. The strand which passes over the idler pulley 33 passes over the roller 34: and thence over the idler pulley 51 on the frame A. This strand is wound about roller 3i in the same way which the previously mentioned strand is wound. From the rollers 3st and t9 the strands extend upwardly guided by the rollers 35 and 50 and into the hollow shaft 36 and upwardly therethrough to the winding spool to which it is attached. By reason of the rotation of this winding spool about its vertical and horizontal axes it is simultaneously twisted and drawn upwardly.

As it is apparent from the foregoing many changes could be made in the construction without differing from the principle of my invention, the subject matter thereof should be considered in an explanatorv and not in a limiting sense.

lVhat I claim and desire to secure by Letters Patent is:

1. In a machine of the type described the combination with a rotatably mounted frame carrying a spool of thread. a rotatably mounted disk mounted thereabove, and a plurality of spools of silk mounted on said disk, of means for laying the strands from the spools of silk about the thread to form a co d. comprising a hollow former mounted above said disk, a sprocket wheel mounted thereon, a vertical standard secured to said sprocket wheel, plurality of idler rollers on said standard upon which said cord is interwound, means for independently rotating said frame disk, and sprocket wheel and means for pulling the strand thus formed through said idler rollers.
